Highlights:
- Major U.S. cities have high rates of interoperability of health data, but variation exists.
- Hospitals’ engagement in interoperability improved by more than 50 percent in 8 major U.S. cities since 2015.
- Hospitals that participate in an HIE and possess the dominant health IT developer’s EHR software within a city
are more likely to engage in interoperability and have information available than hospitals with neither. - Small and independent hospitals in major U.S. cities trail their counterparts in terms of interoperability and providers having information available at the point of care.
